Board or body
Different place. Different numbers.
WOO measures from the board, so heights line up on its leaderboards. SANDIT moves with you, across every board you own. Use it to track your own progression, not to rank against WOO riders.
Which one is for you?
Pick WOO if
Big air is your thing.
- You want your heights on the same leaderboards as your crew
- You want the number on your watch, live
- You prefer to pay once
- You want one today, or live outside the EU, UK or Switzerland
Pick SANDIT if
You ride more than one thing.
- One sensor for kite, wing, windsurf and surf
- Speed and route without a phone on the water
- Kiteloops, tricks, foil and wave metrics
- Hardware upgrades included, and you can wait until Q4 2026
Track every jump. Leave the phone on the beach.
€6,99 a month for founders, sensor included. Nothing to pay until it ships.
Questions
Can I compare SANDIT jump heights with WOO leaderboards?
Not one-to-one. WOO measures from a sensor on the board and itself points out that different mounting positions give different heights. SANDIT is worn on your chest, so use it to follow your own progression.
Does WOO need a phone or watch on the water?
For jumps, no: the sensor records on its own. For speed, distance and a GPS track, yes: the WOO sensor has no GPS, so that comes from a phone or smartwatch recording at the same time.
Is WOO still sold in 2026?
Yes. At the time of writing the WOO 4.0 is listed at €229,95 on WOO’s EU web shop and in kite shops. WOO became an independent company again in July 2026.
Which is cheaper, SANDIT or WOO?
SANDIT costs less in the first two years: €83,88 a year for founders, sensor included, against €229,95 up front. Skip WOO PRO and keep the same WOO for three years or more, and WOO works out cheaper.
